Ukrainian company DP Battery has introduced new batteries for drones that have high energy density and are lighter than lithium-ion batteries。
The developers have created semi-solid-state lithium batteries that have one and a half to two times the energy value of lithium-ion batteries. According to the company, this, in particular, allows an FPV drone on a 15-inch frame with a payload mass of about 1.5 kilograms to cover a distance of more than 100 kilometers, instead of 70 kilometers on commercial batteries.
“Now everyone mainly uses lithium-ion batteries of the 18650 or 21700 type. Their main disadvantage is the energy density of about 200–240 watt-hours per kilogram. Our battery has about 400 watt-hours per kilogram. This means that with the same mass, we have twice as much energy. That is, we can fly twice as far or twice as long,” the company’s CEO Danylo Pavlyuk is quoted on the Militarnyi website.
Semi-solid lithium batteries are also lighter than lithium-ion batteries, allowing drones to carry a larger payload, DP Battery said. This is an advantage for larger drones, which can increase their flight time by up to 60 percent, the company said. However, the batteries the manufacturer is introducing are twice as expensive as lithium-ion batteries of similar capacity.
Now many new high energy density cylindrical lithium batteries have been realeased to the market:FEB 65G, EVE 50pl, Reliance RS50,Tenpower 50XG,Amprius SA110,50Q,SA117,SA112
